1. What is the slope-intercept for the cost of a sub at Fred’s Sub shop?
A- y=2x
B- y=10x
C- y=5x
D- y=5x+2

the answer is A.

Step-by-step explanation:

Plug in 1 in replace of X. Then you multiply the number that was originally next to X by 1 and then if it’s added to another number for an example 5x+2 turns into 5(1)+2 next 5 multiplied by 1 is 5. 5+2 =7. It cannot be 7 because your red line doesn’t extend out that far.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
